Surf photographer Clark Little's pictures of the insides of waves as they break

Hawaii-born Clark Little uses a camera encased in a waterproof casing, which he attaches to his leg with a harness to capture stunning images of the breaking water. Clark spent two decades as a surfer before his wife Sandy commissioned him to take a photo of a breaking wave for their house - kick-starting a lifelong passion.
